The controller also has a separate switching output (16V) for „public“ lighting.
Regulating the speed of the train is a classic pulse-width modulation(PWM), as well as supplemental lighting control. The regulator has the opportunity slow response, switch on / off which simulates the real situation of starting and stopping trains. In case of a short circuit on the track's end provided a transistor current resettable fuse and a thermal sensor.

The regulator are following parts:

Main PCB - PWM control train

PCB secondary PWM for lighting and other outputs for each power supply.
